Abstract

See full text

The disclosure describes a soft-matter electronic device having micron-scale features, and methods to fabricate the electronic device. In some embodiments, the device comprises an elastomer mold having microchannels, which are filled with an eutectic alloy to create an electrically conductive element. The microchannels are sealed with a polymer to prevent the alloy from escaping the microchannels. In some embodiments, the alloy is drawn into the microchannels using a micro-transfer printing technique. Additionally, the molds can be created using soft-lithography or other fabrication techniques. The method described herein allows creation of micron-scale circuit features with a line width and spacing that is an order-of-magnitude smaller than those previously demonstrated.
